Generalized equation of state for refrigerants.

Author(s) : KIM Y., SONNTAG R. E., BORGNAKKE C.

Summary

A new four-parameter generalized equation of state with three reference fluids was developed for predicting thermodynamic properties of the methane and ethane series refrigerants. The 4 chosen characteristic parameters were critical temperature, critical pressure, acentric factor, and the polarity factor proposed in the work. The 3 selected reference fluids were argon, n-butane and 1,1-difluoroethane (R152a). When the characteristic parameters of the refrigerants of interest were not available, an estimation method based on the group contribution method is given. The ideal vapour-compression refrigeration cycle was studied using the newly developed generalized equation of state to verify the accuracy of the work.
